1.Product Overview
The YTTW fire-proof cable is a high-performance electrical solution engineered for ultimate reliability in the most demanding fire emergency scenarios. Featuring a unique construction of high-purity copper conductors and mineral-based insulation, this corrugated copper sheathed cable provides a permanent barrier against heat and flame. As a premium flexible mineral insulated cable and circuit integrity fire survival cable, it combines the life-saving performance of traditional MI cables with a flexible corrugated structure that simplifies installation in complex architectural layouts.
2.Core Product Advantages
Superior Circuit Integrity: Specifically designed to maintain power and signal continuity during intense fire conditions. This cable is engineered to meet rigorous international standards such as IEC 60331 and BS 6387 (for OD ≤ 20mm), ensuring emergency systems remain active when they are needed most.
Corrugated Copper Protection: The continuous corrugated copper sheath acts as a seamless, liquid-tight conduit. This provides exceptional resistance to moisture, water ingress, and chemicals, while doubling as a robust protective earth (PE) conductor with high mechanical impact and crush resistance.
Enhanced Safety (LSZH): The outer Low Smoke Zero Halogen (LSZH) jacket ensures that, in the event of external fire, smoke density is kept to a minimum and no corrosive or toxic halogen gases are released, facilitating safer evacuation and protecting sensitive electronic equipment.
Flexible Installation Design: Unlike rigid MI cables, the YTTW's corrugated metal sheath allows for easier bending and routing. This flexibility significantly reduces labor costs and installation time in tight spaces and complex cable trays without compromising fire survival ratings.
